HOW GLOBAL WARMING AFFECTS THE MONSOON
Monsoon
Monsoon is defined as the seasonal changes in the atmospheric circulation. The
monsoon is usually referred to the seasonally changing pattern. The term monsoon is first
used in English in British India. Now it is used in India, Bangladesh, and Pakistan.
The major monsoon systems of the world consists of the west African and Asia
Australian. The monsoon season in India brings along a heavy rainfall along the west
coast between June and September (South east monsoon) somewhere between mid
October and December (North West monsoon).
SOUTH WEST MONSOON
The southwestern summer monsoons occur from June to September. The
southwest monsoon first hits the Western Ghats of the coastal state of Kerala and India.
The Bay of Bengal branch of southwest monsoon flows over the Bay of Bengal heading
towards north east India and Bengal.
The Indian agriculture is mostly dependent on rain for growing crops like
cotton, rice and oilseeds. The monsoon is widely welcomed by city peoples as well, for it
provides relief from the summer. Bangladesh and certain regions of India like Assam and
West Bengal heavy floods during this season.
NORTH EAST MONSOON
The Northeast monsoon mostly occurs between mid-octobers to
December. This causes the cold wind to sweep down from the Himalayas and IndoGangetic plain towards the Deccan peninsula. When compare to south west monsoon we
get heavy rainfall from North West monsoon. This is also known as the retreating
monsoon. In southern Asia, the northeastern monsoon takes place from December to
early March. Meanwhile a low pressure system develops in south-east Asia and Australia.
Winds are directly towards Australia this is known as monsoon trough.
GLOBAL WARMING AND MONSOON
As the global warming continues, the monsoon season in many areas will
became very extreme. The rain and winds became very severe complications can occur.
As the monsoon streams increase the more rainfall there is more floods and droughts.
Droughts also became more common for increase of temperature.
As the ground became dry, that increases the extreme sand and dust storms.
The monsoon first hits the coastal regions. The coastal regions can develop strong violent
wind.
A larger amount of rain will be brought by the storms the higher the temperature's
rise. As the global warming causes the monsoon move to the other regions of the world,
it can leave the areas that usually experience to monsoon dry.
Environmentalist Anil Agarwal, explained “the monsoon shows how nature uses weak
forces rather than concentrated forces to do it work. Just think: it takes a very small
temperature differences to carry as much as 40,000 million tones of water from the
oceans across thousands of miles to dump it as rainfall over India. This lack of
knowledge of nature’s ways is at the core of the environmental crisis”.
